Analysis on Effect and Relevant Factors of Ultrasound-Guided Lauromacrogol Sclerotherapy to Benign Thyroid Cyst

摘要

Purpose: lauromacrogol sclerotherapy was implemented through ultrasound-guided puncture of thyroid cyst for discussing the therapeutic effect to lauromacrogol hardening thyroid cyst. Method: 50 patients accepting thyroid cyst puncture sclerotherapy in ultrasonography department of our hospital were selected, cystic cavity volume was >=2cm~3, all patients were benign according to cytopathology diagnosis, and they were respectively followed at 1st, 3rd and 6th months after operation. Curative effect was evaluated as follows: the therapy was invalid if cystic cavity volume was reduced by <50%, the therapy was valid if the volume was reduced by >=50%, and the patient was cured if the volume was reduced by >=90%. Results: cyst base line and volumes at the at 1st, 3rd and 6th months after treatment were respectively 8.02+-6.51 cm~3, 6.12+-2.23 cm~3, 3.13+-2.43 cm~3 and 2.01+-1.58 cm~3; the cystic cavity volume was reduced by (72.4+-23.5.7)% on average; cumulative efficiency was 84.0% (42/50), cure rate was 76.0% (38/50); 12.0% (6/50) cysts should undergo sclerotherapy again since they was increased or not reduced compared with the base line 1 to 3 months later. Conclusion: ultrasound-guided puncture lauromacrogol sclerotherapy to benign thyroid cyst was safe and effective, and it reached the maximum therapeutic effect within 6 months.
